Read the following paragraph and write the answers to the questions based on it.
Reproduction is an important process for the survival of an organism. Asexual reproduction occurs in different ways in plants. E.g. Vegetative propagation, fragmentation, budding, spore formation etc. Gametes are formed for sexual reproduction. In the animal kingdom, various methods like budding, binary fission, and parthenogenesis are used. There is no difference between males and females in the animals in which these methods are observed. The method of regeneration also creates new organisms. But regeneration is not the real method of reproduction. Regeneration is the process of healing wounds, creating new organs. This ability has completely disappeared in the developed animals. Modern research is being done on the method of sexual reproduction, e.g. Cloning. So, in the future women will be able to create their own offspring without a father.
- How do living organisms maintain their own species continuity?
- What are the methods of asexual reproduction in animals?
- Why is it said that regeneration is not the real method of reproduction?
- What are the different methods of reproduction in plants?
- What modern breeding methods are being researched in developed animals?
